* [Bug nscd/5216] New: glibc 2.7 compilation problem on alpha due to PTR_MANGLE and PTR_DEMANGLE

Build log can be found here:
http://buildsys.zero42.at/koji/getfile?taskID=52759&name=build.log
For every arch, PTR_MANGLE and PTR_DEMANGLE defines are in
sysdeps/unix/sysv/linux/<arch>/sysdep.h. But for alpha this is not true. The
defines are in sysdeps/unix/alpha/sysdep.h and unix/sysv/linux/alpha/sysdep.h
includes the first. I don't know if this is a mistake or by design...
However, nss/nscd do #include "sysdep.h", which should pull in both headers,
shouldn't it? Well as you can see in the build log that doesn't seem to work out...
(Since the problem occurred at nscd, I post this with component nscd...)

No idea what's going on, the report doesn't have enough information.

Created an attachment (id=2062)
--> (http://sourceware.org/bugzilla/attachment.cgi?id=2062&action=view)
patch that moves PTR_MANGLE for alpha
I'm running into the same problem. My host is x86_64-unknown-linux-gnu and my
target is alphaev56-unknown-linux-gnu.
I'm attaching a patch that moves PTR_MANGLE from sysdeps/unix/alpha/sysdep.h
into sysdeps/unix/sysv/linux/alpha/sysdep.h just for consistancies sake.
PTR_MANGLE was inside of a ifdef __ASSEMBLER__ in sysdeps/unix/alpha/sysdep.h.
Moving it below the #endif /* ASSEMBLER */ in sysdeps/unix/alpha/sysdep.h has
the same result of putting it in the bottom of
sysdeps/unix/sysv/linux/alpha/sysdep.h. Which is where it exists in the rest of
the architectures.
Also, in every architecture besides alpha, the #if defined NOT_IN_libc &&
defined IS_IN_rtld contition has #else. alpha has a #elif defined PIC. The
attached patch changes that #elif defined PIC to a #else.
With these changes I no longer get undefined references to PTR_MANGLE and
PTR_DEMANGLE. This is what I'm now seeing.

I think the full build log does contain everything and although my explanation
wasn't very comprehensive and well written, since I was in a hurry, I think it
contains everything you need.

The thing is, in non PIC mode, rtld.o is not in the libc.a (or hasn't
the symbol that the libc uses for PTR_MANGLE which is the same), so PIC
is definitely special cased.
Attached is a patch that fixes the issue for Debian, and let alpha
build, at the expense of disabling MANGLING in the non PIC case, but
googling showed that the issue is known, and that nobody really cares
about it.

The thing is, in non PIC mode, rtld.o is not in the libc.a (or hasn't
the symbol that the libc uses for PTR_MANGLE which is the same), so PIC
is definitely special cased.
Attached is a patch that fixes the issue for Debian, and let alpha
build, at the expense of disabling MANGLING in the non PIC case, but
googling showed that the issue is known, and that nobody really cares
about it.

Alpha is not in the main tree anymore since we have no maintainer. Somebody has
to step up and volunteer to be the maintainer of the alpha ports tree or nothing
will happen.

Well. What do you want to say?
* I cannot add patches to Fedora; policy doesn't allow
* I cannot send patches to bugzilla; Noone will care
So what shall I do?
What skills will glibc alpha tree maintainer need? Maybe I have to do it myself,
if nobody else steps up, because the current situation is acceptable...

I've been working to port a few things to mips/alpha/hppa, and I'm running into
this too. {specifically on the alpha}
I've applied the patch attached here and it fixed some of my issues, but still
get the attached build errors.
I've looked at the header, but don't know what exactly the defines are messing
with. Can I set a #define that will be a temporary work around for this so the
correct case will get __pointer_chk_guard into the mix?

Greg. I have a few more patches for 2.9.
Maybe the PTR_MANGLE is also outdated already for the latest 2.7.
I'll attach all patches that I have for 2.9 at the moment.

Please note. The currently attached patches do work for 2.9. I'm currently
unsure which patches you'll need for 2.7..

Well I found one for 2.7 that was almost identical to the one attached, I kicked
off the compile last night and let it rip, and it seems to have worked.
The difference seems to be the "elif defined PIC" section.
I'm also assuming with this particular patch this bug migh be marked fixed.
This is it:

Alright. If that works for you that's fine.
There's still the question who is going to put the 2.9 patches into upstream
sources?
Since there's no glibc alpha maintainer? *cry*
